Question

how are the aerobic and anaerobic systems different? (1 point)
the aerobic system uses glucose or glycogen to produce energy, and the anaerobic system does not.
the aerobic system does not require oxygen to produce energy and the anaerobic system does.
the aerobic system is needed for immediate energy use and the anaerobic is needed for activities that last over three minutes.
the aerobic system is for medium - intensity sustained activities and the anaerobic is for shorter high - intensity activities.

Explanation:

El sistema aeróbico utiliza oxígeno para producir energía a partir de nutrientes como glucosa y es adecuado para actividades de intensidad moderada y duración prolongada. El sistema anaeróbico produce energía sin oxígeno y es más adecuado para actividades de corta duración y alta intensidad.

Answer:

The aerobic system is for medium - intensity sustained activities and the anaerobic is for shorter high - intensity activities.
